2 Claims. (Cl. 56--25) The invention relates to a grass mowing attachment, and more especially, to this type of attachment for a motor vehicle.

The primary object of the invention is the provision of an attachment of this character, wherein a sickle cutter bar is driven directly from the engine within a motor vehicle, such as a truck or the like, and is serviceable for farm work or other similar jobs, the attachment being of novel construction, and is unique in the equipment, it being readily and easily controlled and will out long or-short grass, weeds or the like through power transmitted thereto from the power unit of the vehicle.

Another object of the invention is the provision of an attachment of this character, wherein it is designed particularly for service with Jeeps, and is mounted thereon with ease and dispatch, and is also removable in a like manner, so that the vehicle can be used for miscellaneous purposes, and for the mounting of the attachment to the vehicle there being no changes required in the original set-up, that is to say, the chassis frame and motive unit installed therein.

A further object of the invention is the provision of an attachment of this character, which is simple in construction, thoroughly reliable and eflicient in operation, strong, durable, having maximum cutting speed, susceptible of adjustment to working and non-working positions, possessed of long range driving, one man controlled, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which show the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawings Figure 1 is a vertical transverse sectional view through a motor vehicle, showing the attachment constructed in accordance with the invention applied thereto.

Figure 2 is a fragmentary bottom plan view thereof.

Figure 3 is an enlarged fragmentary sectional view through the train of gearing from the motor unit of the vehicle to the attachment substantially along line 3-3 of Figure 2.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3 looking in the direction of the arrows.

Figure 5 is a fragmentary plan view, partly 2 broken away of the sickle bar connections for th driving thereof.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the -at- V tachment constructed in accordance with the invention, comprises a gearing casing or housing It, which is of a size to contain a train of driven gears I I, I la and I lb constituting a transmission for power from the engine l2 installed within a vehicle, only a portion of the latter being shown, to the. attachment. This casing or housing I0 is made fast to the transmission box l3 of the engine l2 in any suitable manner to vertically depend beneath the flooring to a truck body I4, and its supporting chassis [5, only a portion of these being disclosed.

United with this casing or housing I0 is the detachable coupling head [6 of a shaft tubing ll, which extends laterally at an outward inclination beneath the chassis frame [8 to one side of the vehicle body l4, and such shaft tubing 11 can be manually raised or lowered by a chain connection [9, on a crank 20 of a lift rod 2! having bearing in hangers 22 and 23, respectively, suspended from the chassis frame, the rod being fitted with a throw lever 24, rovided with a manually operated latch 25 co-acting with a segment shaped tooth keeper 26 on the body It and in convenient reach of the operator of the vehicle therein.

Within the tubing I! is a driven shaft 21 which has beveled gear connections 28 within the coupling head l6, and hinged at 29 to the outer end of this tubing I! is a sickle bar guide 30, fitted with a reciprocating sickle cutting bar 3|, the shaft 21 being operatively connected with such bar 3! by beveled gear connections 32 actuating wrist-pin eccentric 33, having its wrist pin 34 linked at 35 to the said bar 3| for the reciprocation of the latter for grass cutting purposes.

The guard 39 has connected thereto a lifter rod 36, which through the throw arm 3! pivoted to the head [6, together with a link 38 and bell crank 39, is raised and lowered manually from an operating lever 46, its arbor 4| being journaled in the hanger 22 and is provided with a hand release latch 42 co-acting with the keeper 26, as best seen in Figure 2 of the drawings.

The tubing H is braced by a flexible tie hanger :33 connected to the same and the chassis frame of the vehicle.

The attachment in its entirety is built for detachment from the vehicle, so that the latter can be used with or without the same, and when without can be employed for various purposes common to vehicles of this type. In the attaching and detaching of the attachment to and from the vehicle, there is required no change in the structural make-up of the latter for this purpose, excepting that the side guards, not shown, necessarily have to be removed. To accomplish the detachment of the unit from the vehicle, it is only necessary to detach the casing from the transmission box l3, detach the hangers 22 and 23 from the chassis l5, detach the segment tooth keeper 26 and a supporting bracket 43 likewise from the frame or chassis l5, whereupon the unit may be entirely removed from the vehicle.

The attachment in the working thereof is quick cutting, and is one man controlled, it being positive in action and possesses strength and durability, as well as readily and easily controlled. The attachment when not in actual use can elevatedl from a working position on. the vehicle, and is latched in this position until service is required thereof.

' W liat is claimed is:

1. A grass mowing attachment fora vehicle including albottom chassis frame and an engine, comprising a housing secured to the bottom of saidframe, a tube arranged below' said frame and projecting beyond the latter, a driven shaft mounted in 'said' tube, gearing arranged in said housing for connecting one end of said driven shaft to said engine, a sickle bar guide swingably connected to the other end of said tube, a chain having one end connected to said'tube, a lift rod provided with a crank connected to the other end of said chain, hangers for dependingly supporting said lift rod from said chassis frame, a throw lever for moving said lift rod, a cutting bar reoiprocabl'y connected to said sickle bar guide, an"eccentr-ic mounted on said tube, a link connecting said eccentric to said cutting bar, and

means connecting said eccentric to said driven shaft.

2. A grass mowing attachment for a vehicle including a bottom chassis frame and an engine, comprising a housing secured to the bottom of said frame, a tube arranged below said frame and projecting beyond the latter, a driven shaft mounted in said tube, gearing arranged in said housing for connecting one end of said driven shaft to said engine, a sickle bar guide swingably connected to the other end of said tube, a chain having one end connected to said tube, a lift rod provided with a crank connected to the other end of said chain, hangersfor dependingly supporting said lift rod from said chassis frame, a throw lever for moving said lift rod, a cutting bar reciprocably connected to said sickle bar guide, an eccentric mounted on said tube, a link connecting said eccentric to said cutting bar, means connecting said eccentric to said driven shaft, and a lifter rod connected to said sickle bar guide.
